There are a number of ways to become an architect:
1. You can become an architect by working and learning in an architect's office only. In fact, as long as you have 8 years of experience working under a licensed architect and pass the Architect Registration Exam (ARE), most of the states in the US will allow you to be licensed as an architect.
The problem with this approach is: it takes too long. Most people who have not been to an architectural school simply work as drafters or other low level jobs, and they often have problems in drawing a good section because they have not been trained to understand space and the overall concept of architecture or buildings. They probably cannot pass the ARE either because they have a terrible time in trying to pass the design and the structural portion of the exam.
2. You can go to an architectural school and earn an architectural degree, and then work a few more years in an architect's office and pass ARE, and become an architect. The problem with this approach is that you will have a terrible time in making the transition from architectural schools to architectural practice.
You can try to learn architectural practice by reading "The Architect's Handbook of Professional Practice" (AHPP). The problem is AHPP has too many pages (1028 pages), and it is expensive (about $250 each). Most people will share an office instead of buying it himself or herself.
It is good to read AHPP from cover to cover if you have the time. The problem is that few people have the time to read the whole AHPP. Even if you do read the whole AHPP, you may not remember the important issues anyway. You need to reread the material several times before you can remember much of it.
Reading the AHPP from cover to cover without a guidebook is a difficult and inefficient way of learning architectural practice, because you do not know what the most important things for architectural practice are.
